Joachim looks like both his mother and father equally combined, but when I recently saw a photo of his great grandfather, King Leopold III (on the picture comparison I made), I can't help but think he resembles him a lot, too.
(I don't own the photos: Credits to their owners)
Curly blonde hair, blue eyes, the pointed-ness of nose... (if only we have an authentic colored photo of Leopold III...)
The more Joachim grows older, I think, he will resemble King Leopold III more and more.
I have died scrolling down and reading the entire 39 pages of the thread for Royal Heights and the only reasonable answer I got is … if Prince Amedeo is 187 cm (courtesy of Blue_, thanks^^), from pictures I could assume that Joachim is 3-4cm shorter, so presumably, he is between 183-184 cm (6'0..)
From the engagement photo of Amedeo and Lili with the siblings, Maria Laura and Luisa Maria, I presume, have the same height with no heels (or maybe Luisa is 1-2 centimeters smaller; that difference is too subtle that's why they appear to me as same height). With Amedeo as basis, I can assume their height is between 174-175 cm (or if Luisa is indeed smaller, she might be 172-173 cm). (In American: 5'7.. - 5'8...) Very tall women!
As for Laetitia Maria, I'm not so sure how to estimate her height. I'd like to think she is between 150 cm (yay, my height :S) to 153 cm.
(Please Laetitia, be smaller than what I think so that I won't look like Joachim's god-child~~)
Forgive me if I'm saying nonsense. Thanks for understanding : )
